It is roughly oval in plan, measuring about 29 metres north to south and 32 metres east to west, and the ground inside it sits noticeably higher than the surrounding fields. What makes the construction particularly interesting is the way the defensive boundary changes character depending on where you look: on the northern to south-south-eastern arc it takes the form of an earthen bank standing about a metre tall on the interior, while everywhere else the boundary presents as a steep scarp dropping as much as 3.4 metres. An external fosse, a shallow defensive ditch, runs around the north-eastern to south-eastern section and would once have added to the sense of a well-considered boundary.

This is a rath, the most common type of ringfort found across Ireland, typically dating from the early medieval period, roughly the fifth to twelfth centuries. Raths were the enclosed farmsteads of prosperous farming families, the bank and ditch serving less as true military fortifications and more as a statement of status and a practical barrier against livestock straying or predators entering. The entrance here faces east-north-east and is a generous 4.3 metres wide, approached by a causeway across the fosse, the kind of feature that implies a deliberate, formal threshold rather than a simple gap in the earthwork. Beneath the interior, there may also be a souterrain, an underground stone-lined passage or chamber of the sort often used in early medieval Ireland for storage or as a place of refuge in times of trouble.
